Understanding the Benefits of PFAS Removal in Aurora’s Water Supply: A Guide by Water Works

The removal of Per- and Polyfluoroalkyl Substances (PFAS) from Aurora’s water supply is crucial for maintaining public health and environmental sustainability in Colorado. These chemicals, often referred to as “forever chemicals,” present persistent challenges due to their widespread use and durability. This guide will explore the significance of PFAS removal, the methods being utilized, and the ongoing efforts to ensure clean drinking water for Aurora residents.

Presence and Risks of PFAS

PFAS are pervasive in Aurora’s water supply, infiltrating both surface water sources, like rivers, and groundwater from wells. These substances have numerous industrial origins, including manufacturing processes and products like firefighting foams and stain-resistant coatings. The health risks associated with PFAS exposure are alarming; research indicates a connection to various adverse outcomes, including increased cancer risk, immune system issues, adverse reproductive outcomes, and liver damage. Vulnerable populations, including young children and pregnant women, face heightened risks due to PFAS exposure. Additionally, PFAS contribute to environmental degradation, affecting wildlife and ecosystems. Effectively treating water supplies to remove these harmful substances is therefore essential for safeguarding public health and protecting local ecosystems. Implementing robust PFAS removal strategies ensures that Aurora residents have access to safe and clean drinking water, free from these persistent contaminants.

Treatment Technologies

To combat PFAS contamination in drinking water, Aurora Water employs several advanced treatment technologies. **Granular Activated Carbon (GAC)** is a vital element of the Prairie Waters System, which recaptures water from the South Platte River. GAC effectively adsorbs long-chain PFAS compounds like PFOA and PFOS, yet there are limitations in its effectiveness against shorter-chain compounds. Another highly effective method is **Reverse Osmosis (RO)**, which utilizes a semi-permeable membrane to block even the smallest impurities, ensuring that harmful substances are effectively filtered from the water. RO systems are especially important for households concerned about their drinking water quality and can be integrated into residential water purification systems. **Ion Exchange Resins** work by exchanging harmful PFAS ions with less harmful ions, effectively lowering their concentration in treated water. This technology is often paired with other filtration methods to enhance overall system performance, providing a robust solution to PFAS contamination. By utilizing a combination of these technologies, Aurora Water ensures comprehensive removal of PFAS, maintaining high water quality standards for the community.

Ongoing Efforts and Initiatives

The City of Aurora is engaged in several proactive measures to address PFAS contamination. **Regular Testing** is a cornerstone of these efforts, with the Colorado Department of Public Health and Environment (CDPHE) launching a voluntary testing program for PFAS levels in drinking water. Strong participation from water utilities ensures that monthly testing is conducted to monitor compliance with safety guidelines. Additionally, **Pilot Programs** are being operated at the Binney Water Purification Facility to enhance current filtration capabilities. These pilot plants test various treatment methodologies with the goal of improving the effectiveness of PFAS removal processes. **Public Awareness Campaigns** are also integral, as educating the community about PFAS issues and water safety fosters informed citizens who can advocate for clean water initiatives. Aurora Water actively engages residents through public information sessions and education programs, emphasizing the importance of understanding water quality and ongoing treatment efforts. These combined initiatives demonstrate Aurora’s commitment to combating PFAS contamination and ensuring a healthy environment for all its residents.

Compliance with Standards

Aurora Water is dedicated to ensuring that drinking water meets or exceeds state and federal safety standards, including the recent regulations from the Environmental Protection Agency (EPA) targeting specific PFAS compounds. Regular monitoring and stringent testing protocols are in place to detect any fluctuations in PFAS levels promptly. When issues are identified, Aurora Water takes immediate action to address them, utilizing the most effective treatment technologies available. Compliance with these standards not only protects public health but also builds trust within the community, assuring residents that their water supply is safe. Additionally, Aurora Water collaborates with state and federal agencies to stay updated on the latest guidelines and best practices for PFAS removal. This proactive approach ensures that Aurora remains at the forefront of clean water initiatives and continues to provide high-quality water to its residents.

Cost and Resource Considerations

Implementing PFAS removal systems can carry significant costs, particularly for smaller communities. However, Aurora Water is committed to overcoming these financial challenges through various funding options. Grants and federal support, such as those provided by the Bipartisan Infrastructure Law, are available to assist local governments with necessary infrastructure investments. These funds help offset the costs of advanced treatment technologies like Reverse Osmosis and Ion Exchange Resins, making PFAS removal more feasible for the community. Additionally, Aurora Water explores partnerships with private sector entities and seeks community support to ensure sustainable funding for ongoing water purification projects. By strategically managing resources and leveraging available financial assistance, Aurora Water can effectively implement and maintain PFAS removal systems, ensuring long-term access to clean and safe drinking water for all residents.

Conclusion

In summary, the importance of PFAS removal for clean and safe drinking water in Aurora cannot be overstated. With effective treatment technologies, continued monitoring, public education, and community support, Aurora is working toward a safer and environmentally sustainable future. Residents concerned about their water quality can explore services such as PFAS removal to ensure their homes benefit from the highest standards of water purification. Additionally, for those in Aurora, comprehensive water softener and purification solutions are available through local experts. By addressing PFAS contamination head-on, Aurora Water is committed to protecting the health and well-being of its community.
